How Often to Change Your 10x20x1 Air Filter?

Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.

Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.

Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home. The extra strain on the HVAC system causes higher energy bills. Regular home air filter replacements can prevent expensive system repairs or replacements down the road.

You should change your filter more frequently if you notice:

  • Household dust build-up
  • The air isn’t cooling as is used to
  • There’s more dust near the air vents
  • A dirty filter surface
  • Higher energy bills
  • Burning smells near your HVAC system.

10x20x1 Furnace Air Filter

Filter King 10x20x1 size furnace filters keep the air flow coming into a home while at the same time keeping airborne irritants out. Your furnace filters are an important part of any air conditioner system and provide protection to your ducts and home. The furnace filters in an HVAC system consist of a tight mesh weaving with a cardboard edge designed for easy installation. When air passes through the air filters any accompanying small and large particles are captured and absorbed while the air flow is allowed to pass. Over time, the amount of captured particles begins to fill in the mesh weaving and requires you to replace the old filters with new ones.

Dirty air filters in your home affect its overall indoor air quality, affects how comfortable and safe the air inside is to breathe. Over time, any issues with a dirty filter will become worse and eventually begin to affect your home as a whole. New furnace filters will provide a layer of protection to your home while at the same time allow air to efficiently pass through. In order for your HVAC system to keep running on optimal performance, replace filters every 90 days. Filter King 10x20x1 air filters rank 8, 11 or 13 on the MERV (Minimum Efficiency Reporting Value) scale as an eight. Our filters are capable of blocking out irritants from the air passing through them. They can trap irritants like, 

  • Pollen
  • Household Dust
  • Mold Spores
  • Dust Mite Debris
  • Bacteria
